Vitamin H, or Biotin, is a water-soluble B-complex vitamin (B7) that helps the body convert food into energy. It supports the metabolism of carbohydrates, proteins, and fats, making it essential for overall energy production.
Since biotin is water-soluble, it is not stored in the body and must be obtained regularly through diet. It is also commonly referred to as the “beauty vitamin” due to its beneficial effects on hair, skin, and nails.
Natural Sources of Vitamin H
Biotin is found in a wide variety of foods, especially protein-rich and plant-based sources.
Animal-Based Sources
1. Egg yolk – Richest natural source of Vitamin H.
2. Liver and kidney (organ meats) – High in biotin and other B vitamins.
3. Fish (salmon, tuna, sardines) – Provide biotin along with omega-3 fatty acids.
4. Meat (chicken, pork, beef) – Good for protein and biotin.
5. Dairy products (milk, cheese, yogurt) – Contain moderate amounts of biotin.
Plant-Based Sources

Health Benefits of Vitamin H (Biotin)
1. Promotes Healthy Hair
Vitamin H is widely recognized for its role in preventing hair thinning and hair loss. Biotin supports keratin production, a protein essential for strong and shiny hair. It is often included in shampoos, serums, and supplements designed for hair growth.
2. Improves Skin Health
Biotin deficiency can lead to dry, irritated, and flaky skin. Adequate intake of Vitamin H helps maintain skin hydration, elasticity, and a natural glow. It is also effective in reducing acne and dermatitis.
3. Strengthens Nails
Brittle, weak, or splitting nails are often a result of biotin deficiency. Regular intake of Vitamin H strengthens nails, making them less prone to breakage.
4. Supports Metabolism and Energy Production
Vitamin H helps enzymes break down carbohydrates, fats, and proteins into energy. This makes it essential for maintaining energy levels and reducing fatigue.
5. Regulates Blood Sugar Levels
Biotin improves glucose metabolism and may help people with type 2 diabetes by regulating blood sugar levels when taken with other treatments.
6. Promotes Brain Function
Vitamin H plays a role in neurotransmitter activity, supporting better concentration, memory, and overall brain health.
7. Aids Pregnancy and Fetal Development
Biotin is important during pregnancy as it helps in fetal growth and development. Pregnant women often require higher amounts of Vitamin H.
8. Improves Heart Health
Biotin supports metabolism and helps in maintaining good cholesterol levels, contributing to better cardiovascular health.
9. Supports Muscle and Tissue Health
Biotin assists in the repair of muscles and tissues, making it valuable for athletes and physically active individuals.
Recommended Daily Intake of Vitamin H
The daily requirement of biotin varies depending on age and health conditions.
○ Infants (0–12 months): 5–6 mcg
○ Children (1–8 years): 8–12 mcg
○ Teens (9–18 years): 20–25 mcg
○ Adults: 30 mcg
○ Pregnant women: 30 mcg
○ Breastfeeding women: 35 mcg
Most people can meet their daily requirement through a balanced diet, but supplements may be recommended in certain cases.
Symptoms of Vitamin H Deficiency
Though deficiency is rare, it can occur due to poor diet, alcoholism, pregnancy, or long-term antibiotic use. Symptoms include:
⌕ Hair thinning and hair loss
⌕ Dry, scaly, or irritated skin
⌕ Brittle nails
⌕ Fatigue and low energy
⌕ Depression and mood changes
⌕ Numbness or tingling in hands and feet
⌕ Poor appetite and weight loss
⌕ Severe deficiency can lead to neurological problems and delayed growth in children.
Vitamin H Supplements
When dietary intake is insufficient, biotin supplements are available in:
Tablets and Capsules
Chewable Gummies
Powder Form
Hair and Nail Care Products (biotin shampoos, oils, serums)
Most supplements contain 5,000 mcg to 10,000 mcg of biotin for enhanced hair, skin, and nail health. However, supplements should be taken under medical guidance to avoid side effects.
Side Effects of Excess Biotin
Vitamin H is generally safe, as excess amounts are excreted through urine. However, very high doses may cause:
Skin rashes
Digestive discomfort
Interference with lab test results (thyroid, vitamin D, hormone levels)
Best Ways to Include Vitamin H in Your Diet
1. Eat boiled eggs instead of raw eggs (raw egg white contains avidin, which blocks biotin absorption).
2. Add nuts and seeds as snacks.
3. Include fresh fruits and vegetables in daily meals.
4. Choose whole grains over refined grains.
5. Take biotin-rich smoothies with bananas, spinach, and yogurt.
Conclusion
Vitamin H, or Biotin, is a vital nutrient that supports healthy hair, glowing skin, strong nails, energy metabolism, and overall well-being. While deficiency is rare, ensuring a diet rich in biotin-containing foods or supplements can help maintain beauty and health naturally.
Adding biotin-rich foods like eggs, nuts, seeds, and vegetables to your diet can prevent deficiency and promote overall vitality. If needed, supplements can be used under professional advice, especially during pregnancy or in cases of hair and nail problems.
By maintaining adequate levels of Vitamin H, you can achieve not only better beauty but also better health and energy.
